AUGUSTUS DAVID KLABER, OF LONDON, ENGLAND.

LETTER-COPYING APPARATUS.

Application filed January 31, 1911.

To all whom it may concern:

Be it known that I, AUGUSTUS DAVID KLABER, subject of Great Britain, residing at London, England, have invented new and useful Improvements in Letter-Copying Apparatus, of which the following is a specification.

This invention relates to improvements in and relating toletter copying apparatus and it refers to apparatus of the class in which the copying is effected by submitting the letter or the like, of which the copy is desired, together with a web of thin paper, to pressure between a pair ofrollers, the paper afterward being wound upon a suitable reel and while thereon cut up into lengths by means of a knife. In copying apparatus of this character as at present constructed the paper when out forms a number of loose sheets which in order to preserve them for future reference, are transferred to a so called letter file or binder, or are otherwise secured together.

The present invention has for its primary object to provide means upon the machine itself whereby the sheets may be secured together after the manner of the leaves of a book so that when out they form as it were a solid body which when removed from the machine may be conveniently handled without fear of loss ofany of the sheets.

The present invention has for its further object to provide an'improved feed for the letters or sheets of paper bearing the matter to be copied, the construction and arrangement of which is such that thefingers engaging the said letters or the like are withdrawn below the plane of the surface sup porting the said letters or the like during the non-effective portion of their travel. By this means the necessity of waiting until the fingers reach the limit of their non-effective movement is avoided and the letters or the like can be placed upon the feed table immediately the fingers reach the end of their forward movement.

The invention also provides for the increase in the effective length of the circumference of the reel or bobbin upon which the copying paper is wound so that it may be varied according to the size of the sheets of paper bearing thematter to be copied. The invention finally provides an improved method and means for mounting the roll of copying paper so that the spindle heretofore required to support it, is dispensed Specification of Letters Patent.

trating a machine embodying the various improvements above speclfied and in wh1ch:-

Figure 1 is a side elevation of the machine. Fig. 2 is a plan showing the arrangement of the take up roll or bobbin. Fig. 3 is a plan with the paper container omitted. Fig. 4 is a front elevation of the receptacle for the copying paper with the lid open. Fig. 5 is a cross sectional view showing the gumming device. Fig. 6 is a sectional view to a larger scale of the gumming device shown in Fig. 5. Fig. 7 is an enlarged sectional view of one end of the adjustable longitudinal members of the take up roll. Fig. 8 is an enlarged cross section of the can tainer for the moistening pad. Fig. 9 is a cross section of the copying paper receptacle. Fig. 10 is a plan view of the knife in its inoperative position and Fig. 11 is a similar View showing the knife in its operative position.

Referring to the accompanying drawings, a a indicate side members of the main frame of the apparatus which are connected in any suitable manner and which are provided at a? with perforations for a transverse shaft a driven by means of a pulley a Figs. 2 and 3 which received motion by means of a belt, not shown, from a second shaft a and which may be driven by hand or from a suitable source of power, such as an electric motor.

Secured to one end of shaft a is a cam 12 upon the periphery of which bears a roller 6 mounted upon the end of a rod 12 slotted at b for the passage of a screw 6 tapped into the side frame a. The rod 6 is connected at its outer end to a lever b upon a shaft Z2 pivotally mounted at b upon an extension I) of frame a. The lever 72 is drawn inward by means of a spring 6 connected at one end to frame a and at the other end attached to lever 6 The lever 72 at its upper end is connected to a short link 0 which link at its opposite end is connected to a short lever 0 secured to one end of a transverse bar or rod 0 supported at each end upon slippers 0 sliding upon parallel rods 0 disposed beneath the feed table cl upon which the letters are placed and from which they are fed forward between the rollers e f together with the copying paper indicatedbyir. The rod 0 'has secured to it pins or projections g which work in slots on the table d and when in their operativepositions, project above the level of the said table d. The rod 0 is free to rotate in the slippers c and consequently as the lever moves inward under the action of the spring 6 the rod is maintained in a position such that the projections g are in the position shown in Fig. 1 and a letter or the like placedon table (Z will be pushed forward to and carried by; the paper as around the rollers e and f. Upon the return of the rod 0 the said rod is partly rotated and the projections thereon are disposed below the plane of the feed table as shown on dotted lines in Fig. 1. By this means the table is available immediately the return movement of the rod 0 commences and there is no necessity to wait until it reaches the end of its backward movement before thenext document can be placed in position on the feed table. To insure the proper rotation of rod 0 at the end of its outward stroke, a pin g is arranged in the path of the lever 0 and acts as a tappet coming into contact with the edge of lever as it reaches its terminal position see Fig. 1. Mounted upon each end of the shaft a are disks N provided with holes adapted to receive the ends of the transverse rods n which form the take up roll upon which the paper is wound after the copying has been effected by means of the aforesaid rolls 6 f. The rods n are adjustable so far as their position relatively to the center of the disks are concerned and with this object there are provided other holes n in the disks with which engage spring pressed studs of, retained in the ends of the rods n by means of collars such as a the outer face of which abuts against the end of short screws 02. in Figs. 2 and 7 When it is desired to alter the position of the rods, the studs are pressed inward until free of the holes, when the rods may be removed and placed in engagement with holes nearer to or farther away from the center according as it is desired to reduce or increase the amount of paper taken up at each rotation of the spindle a The end of thecopying paper at is secured by means of the spring plate 2' which presses the end of the paper into the recess 2' in the transverse rod 2' in Fig. 5.

Formed integral with or secured in any convenient manner to the disks n is a transverse member y' Figs. 1, 2, 5, 6 and 10 slotted at j to permit the passage of the knife 5 (see. Figs. 10 and 11) when cutting the copying paper coiled'on the take up roll.

The knife before referred to, see Figs. 10

andll, is slidably mounted upon a cross bar 5 supported at each end upon frame a. The knife is-provided with inclined slots at 5 for the passage of studs 5 whereby theknife is secured to the frame and at the same time the inclination of the slots secures the necessary sliding and longitudinal motion of the said knife. The operation of the knife is efiected by means of a lever 6 pivoted at 6 to the frame a and connected by means of a link 6 with the said knife 5. In order that the knife may not be actuated except at such times as the slot f is in the position to receive it, a lever 7 is mounted upon the inside of the frame a and carries a roller 7 which roller bears against the periphery of the disk N until such time as the said disk permits the roller to rise and the outer end of the lever to fall. As the outer end of lever 7 normally projects into the path of the knife 5 see Figs. 10 and 11, the removal of said end from said path will permit the knife to be actuated. The member j is extended at j and forms a rigid surface against which bears a roller j conveying gum from a roller 7' driven from shaft (0 by a belt and dipping into a reservoir 9' containing gum or other adhesive and which receptacle carries an adjustable wiper j by which the amount of the gum on roller j is regulated. The reservoir j* runs transversely between the frames at a and is mounted upon brackets j secured to the frames at a and having bearings for a shaft y Figs. 5 and 6. Mounted upon shaft '1 are levers 3 which carry the rollers j A spring is provided for each lever 3 the tendency of which is to keep the said arm always bearing away from the gum roller 9' so that the gum is applied to the paper. As however, it is not required that the gum shall be applied except for a very short period during the rotation of the take up roller, the levers are each provided with rollers which bear against the periphery of one of the disks N and by this means the roller j is held clear of the paper except at such times as the recess in the disk permits it to move inward and apply the gum to the copying paper. 7

The copying paper w before referred to is wound upon a cardboard or other cylinder Z, see Fig. 9 and it is disposed within a circular receptacle Z which is mounted at the upper ends of the frames (1, a as shown in Fig. 1. The receptacle Z is closed and access isattained to it by means of the door Z which forms a continuation of the body of The roller is supported at'each end by projections which are formed upon the screw or other studs m m supported on the end walls of Z The projections on the screws m m enter the hollow core of the roll and by this means support it without the necessity of employing the usual transverse spindle. In order that the paper roll shall not rotate too freely, I provide a jockey roll a which rests upon the surface of the roll a: and is supported at each end by means of slots n in the inside of the end walls of receptacle Z A radial slot n is also provided communicating with slots 11, so that the roller may be supported clear of the roll so that it does not interfere with the ready removal or replacement of the said roll when required.

here the apparatus is not constantly in use, it is found that the copying paper, which is treated with some suitable hygroscopic substance, is apt to get too dry for use, and in order that this may be avoided, I provide a pad 9 adapted to be moistened and which pad is contained within a perforated case 9 removably secured within the receptacle Z Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1.
